How does Andrew Crayton change over the course of the novel, After the Dancing Days?

Andrew is the severely disfigured young man whom Annie first sees at the train station on the morning that Dr. Metcalf returns from New York City. Annie's apprehension, when first meeting Andrew on the grounds of St. John's Hospital, turns into a friendly bond that alters the course of Andrew's life during the summer of his convalescence. Andrew and his father are estranged because Mr. Crayton believes Andrew should not have enlisted in the army. If Andrew had stayed home to work on the farm, Andrew would never have sustained his disfiguring injuries. Andrew is doubly distressed by his injuries because he will, not only be disfigured for life, but also because it was Andrew's own negligence which precipitated the accident. Andrew was caught off guard when the German gas came rolling into the trenches. Andrew was not able to find his gas mask, which exacerbated the extent of his facial injuries. Andrew forges an unusual friendship with Annie. He is inspired by her compassion and encouragement, which turns his bitterness to hope. Andrew also serves as a lesson for both Annie and Mrs. Metcalf. Annie learns the value of rising above personal trauma, through interacting with Andrew. Mrs. Metcalf, in turn, learns the value of acceptance and tolerance, through the presence of Andrew in the lives of the Metcalf family members. By the end of the novel, Andrew rises above his personal pain to enjoy the success of others. He even decides to move to Topeka, to help with other soldiers still recuperating from their own war injuries.
